 * -How can’t Soda which is an acid, not eat through an aluminum can?**

__Materials__
 * A can
 * Soda (Coke, Pepsi, Thumbs up, etc.)
 * Two equal dimensions plastic containers
 * A Clock

__Procedure__
 * 1) Cut two equal pieces from the can, same dimensions
 * 2) Take one of the pieces and scrape the inner coating on the can
 * 3) Fill each container with the same amount of soda
 * 4) Put each piece of the can into each container
 * 5) Analyze the difference taking place each interval
 * 6) Measure the mass of each piece every interval, as well as take pictures

__How?__ As we know that soda is a type of acid and any acid can eat through aluminum, so why doesn’t this occur? There is a special type of coating on the inner part of every can, which is called polymeric coating, which disables the soda to cause any kind of non-preservative things to occur, such as erosion. __In This Experiment__ I will do the same procedures as I included before. I will be taking the readings every 24 hours, because that will be enough for a good amount of change to occur in the mass of the object. I will take pictures for proof. I will also make a graph of the changes.

Control Variable: The Amount of Soda Independent Variable: The time between each Interval Dependent Variable: The change in mass.


 * -What Would Happen in the Absence of Gravity?**

Gravity is actually the force of attraction in the sense that it pulls things together. Everything you see or feel is actually exsiting because the force of gravity is keeping it together in a matter form, so ait can be seen, smelled, tasted, touched, and heared.

It holds stars and galaxies together. Gravity even enables the Moon and other satellites to orbit the Earth becuase of it force of attraction. Without gravity, it would be impossible for mankind to survive, since we would simply fall off the Earth.

The significance of gravity was first explained by Sir Isaac Newton in 1687 and since then has been recognised, and compared together with friction, as the most important forces within the entire Universe.

If the Universe were to collapse, due to lack of gravity, it is thought that the stars, galaxies and Earth, etc would simply drift through space and time as we see it. The Universe has no known start or finish, no top or bottom and since there is no gravity there is no central pull, so there would be nowhere for everything to gravitate towards, no logical landing point. Everything would simply drift from here to there.

The main point to look upon is also what will happen to the human kind. Gravity is the force that keeps our feet on the ground. Without gravity the human kind would most likely perish. This is because with no gravity there would be no way to stop we the people from floating far into space and way beyond to parts of the universe that have no oxeygen or places that there is nothing to survive off of, there will be no food no oxygen, water, abnd other neccesities. Our senses will fall apart and as we know the human race would perish.

So basically If there is no gravity, we will remain floating in the air, and everything would remain suspended in the atmosphere.
